The Tanyderidae have two hving genera, one antipodal and the other 

 (Protoplasa) with two Nearctic species. 



"The Ptychopteridae have three genera. One of these, Ptychoptera, 

 is found in most parts of the world excepting Australasia, while the other 

 two, Bittacomorpha and Bittacomorphella, are Nearctic. 



The Rhypliidae have seven genera, arranged in three subfamilies. 

 The species, with few exceptions, are from the North Temperate Zone. 



Among the Tipulidae, the tribes Limnobiini, Antochini, Eriopterini, 

 Limnophilini, Dolichopezini, Ctenophorini, and Tipulini are almost 

 cosmopolitan. The tribe Hexatomini has the genus Hexatoma dominant 

 in Europe, and the genus Eriocera cosmopolitan except for the Palaearctic 

 and Australasian regions. The tribe Pediciini reaches its greatest develop- 

 ment in the North Temperate Zone. The Cylindrotominae are holarctic, 

 with one genus (Stibadocera) occurring in the Oriental region. 



Lists of the species of adjoining States and provinces 



The following lists of species are given to supplement the data on the 



New York fauna. 



Maine 



The data for Maine are based largely on the results obtained by the 

 author from a study of the group during a period of fifteen weeks, under 

 the direction of Dr. Charles D. Woods and Dr. Edith M. Patch. Very 

 valuable collections in this State have been made by Mr. Charles W. 

 Johnson, Miss Cordelia J. Stanwood, Dr. H. M. Parshley, Professor 

 Herbert Osborn, Professor A. P. Morse, and others.
